Test material information:
Composition 1
Specific details on test material used for the study:
In order to obtain a homogeneous sample, the test item is liquefied in a water bath before to be used.
The water bath was at a temperature of 42°C.
Flash point:
161 °C
Atm. press.:
1 013.25 hPa
Flash point:
159 °C
Atm. press.:
1 013.25 hPa

Preliminary test result:

The estimated flash-point was 158°C

Main test results:

The lowest temperature at which a flash point was observed was chosen as test item flash point. This value was 159°C.

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item is 159°C at normal atmospheric pressure.
Based on this value and on the test item boiling point (no boiling before decomposition at 250°C), it is not classified as flammable liquid according to GHS criteria.
Executive summary:

The flash point of the test item was determined by the closed cup method according to recognised guidelines and under GLP.

No deviation from these guidelines was observed during the study.

The flash point of the test item is 159°C at normal atmospheric pressure.

Based on this value and on the test item boiling point (no boiling before decomposition at 250°C), it is not classified as flammable liquid according to GHS criteria.

Description of key information

The test item flash point was determined in an experimental key study (Klimisch validity one, according to recognised guidelines).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
159 °C

Additional information

Based on the flash point value and on the boiling point data (no boiling before decomposition at 250°C), the test item is not classified as flammable liquid according to GHS criteria.
